connection

问题 I have an application that uses both grequests and multiprocessing.managers for a combination of IPC communication and Asynchronous RESTful communications over HTTP. It seems that grequests , in using gevent.monkey 's patch_all() method, breaks the multiprocessing.connection module used by the multiprocessing.manager.SyncManager class and its derivatives. This is apparently not an isolated issue, but affects any use case that implements multiprocessing.connetion , such as multiprocessing.pool

问题 We have recently changed our SQL Database server and i was wondering if there would be a script or an easier method of updating all the Excel file connection strings? It would of been alot easier if they used a connection file but unfortunately they were all set manually and we have about 600 reports... Any help is much appreciated.

问题 Last summer, I made a Java application that would parse some PDF files and get the information they contain to store them in a SQLite database. Everything was fine and I kept adding new files to the database every week or so without any problems. Now, I'm trying to improve my application's speed and I wanted to see how it would fare if I parsed all the files I have from the last two years in a new database. That's when I started getting this error: OutOfMemoryError: Java Heap Space . I didn't

问题 I have a HTTP client that sets the Connection header to the following value when I make a request: Connection: close However when the server sends a response, it is setting the header to Keep-Alive: Connection: Keep-Alive This seems intuitively wrong to me, and I am wondering how the client should handle such a response from the server? Also why would a server respond with Keep-Alive, when the client has asked for the connection to be closed, is this valid? According to the HTTP RFC: "HTTP/1
